I found that if you go back far enough in the family tree, you encounter two versions of Adam. one says, "adam EVE adam eve" as parents of Seth, who married eve. another one has pictures, and shows Jesus as his father, and if you follow his line to the father side, you get the first example. if you go a little to the right, you find the same Adam Eve- Jesus scenario, and you get to follow the loop forever. Infinite loops shouldn't happen, so how about we say God the Father is Jesus' parents? Or that God the Father is the parent of Adam and Eve?
On another note, as I was trying to get the screenshots for this, I noticed it was taking a longer and longer time to move around and likewise. this means that all the "namecards" in the tree were also being paid attention to, slowing it down. If whatever engine is drawing the tree stops drawing the tree if it's off the browser, that would fix the problem. If the problem is ignored too long, and you go too far back, the connections get glitchy. Really glitchy. Really really glitchy. I eventually had to open the tree of someone farther down the line to reduce lag.
Another infinite loop I found was from Sceaf Seskef Odan 1 (9CFD-YJL) to this line of people, and back to Sceaf. Here is the line of people, beginning with Sceaf's father.
Magi ben modassen, Loridi hloritha (father in law to Magi), Zalmoxis, Borbysta, Filimer, Gandric, Teatwa, Berig, Hwala, Bedwig, and Sceaf. I don't know why Sceaf is his own great great great great great great great great grandfather, but that is a problem. And yes, I did check whether it was the same Sceaf.
